Anxiety can cause tension and worry even without direct threats, and it negatively affects individuals and society as a whole.
Research shows gut microbiota influences anxiety-like behavior in rodents, with germ-free and antibiotic-treated mice exhibiting reduced anxiety.
Short-chain fatty acids (SCFA) from gut microbes appear to modulate anxiety responses, with SCFA supplementation in antibiotic-treated mice showing increased anxiety, independent of the vagus nerve's influence.
